摘要：
A micro solar driven combined cooling, heating and power (CCHP) system based on organic Rankine cycle (ORC) is proposed and investigated for summer and winter modes. Detailed exergy analyses indicate that 11.7% and 9.8% of total input exergy are useful in winter and summer, respectively. Auxiliary boiler and solar collectors are found to be the highest source of irreversibility for both modes. The effects of several key parameters on the system performance, required collector area and solar fraction are investigated. The system exergy efficiencies are optimised by means of genetic algorithm. Optimum values of turbine inlet pressure, turbine inlet temperature and turbine back pressure are 985.6 kPa, 130 degrees C and 263.1 kPa in summer and 1001 kPa, 120 degrees C and 332.4 kPa in winter, respectively. It is also shown that system exergy efficiency improves from 9.8% to 10.09% in summer and 11.7 to 17.21% in winter under optimum conditions.
